Doctors Upbeat About Report
National Cancer Institute Shows Drop In
Cancer Death Rate In U.S.
By Robert Miller
For years, the medical establishment has been preaching the
virtues of screening tests for cancer, reasoning that the earlier
the disease is detected, the easier it is to treat.
"We'd hoped we were right on this," said Dr. Orion Howard,
director of medical oncology at the New Milford Hospital-Columbia
Presbyterian Regional Cancer Center. "We just didn't always have the
data."
Now doctors have those numbers. The National Cancer Institute, in
conjunction with several university teaching centers and the Centers
for Disease Control and Prevention, has issued its annual report on
cancer deaths in the United States.
The report shows the number of cancer deaths declining 2.1
percent a year between 2002 and 2004. That's double the 1 percent
drop in cancer deaths recorded from 1993 to 2002.
The difference means that thousands of people who might have been
died from cancer are still alive.
"It highlights all the good things that are going on," said Dr.
Edward Chu, deputy director of the Yale Cancer Center in New Haven.
"It has to do with early detection and screening. It has to do
with lifestyle changes," Chu said. "And we've been seeing real
progress in surgical techniques, in radiation therapy and
chemotherapy."
"The report showed mortality declines in several cancers -- most
notably breast cancer, colon cancer and prostate cancer," said
Howard, of New Milford Hospital.
"These are three forms of the disease that doctors can screen
for," he said. "Screening is one of the best tools we have for
reducing cancer deaths."
The report said mortality from lung cancer -- overall, the most
deadly form of the disease -- is declining in men. For women, the
rate of lung cancer deaths is still going up, but at a slower pace.
Chu, of Yale, said this is because women, who were slower to
start smoking cigarettes, have been slower to quit them.
Because 90 percent of all lung cancers are smoking-related, that
means women are behind the curve of behavioral change that's already
benefitting men. As more women stop smoking, he said, this will
change.
"I think in five to 10 years, we're going to see valuable
declines in women's lung cancer deaths as well," Chu said.
Dr. Vincent Rella, an oncologist at the Praxair Cancer Center at
Danbury Hospital, said as people stop smoking, there will be lower
mortality rates in several other forms of cancer -- oral cancers,
bladder cancer and esophageal cancers, among them.
"Of the top 15 types of cancer for men, there are declines in
mortality for 12 of them," Rella said. "For women, it declines in 10
of the 15. A lot of those cancers are smoking-related."
Colorectal cancer is one form of cancer with a declining
mortality rate that's clearly linked to a screening test -- the
colonoscopy -- which is now recommended for everyone 50 years old or
older, or earlier if there are additional risk factors, like a
family history of the disease.
But Dr. Joel Levine, who runs the colon cancer prevention program
at the University of Connecticut Medical School in Farmington, said
colonoscopies can only catch 50 to 60 percent of polyps and early
colon cancers.
"That's good, but it's not great," he said. "You can't put all
your faith in colonoscopies. It's what you do between colonoscopies,
in terms of lifestyle changes -- diet, exercise, obesity -- that's
also important."
Howard, of the New Milford Cancer Center, said oncologists are
now buoyed by new drugs coming on the scene.
"For 30 years, we had one drug to treat colon cancer," he said.
"Now we have six. Of those, five came on the scene in the past 10
years. I'm seeing patients with metastatic colon cancer staying
alive that I know would not have made it a few years ago."
And, Howard said, there are many more targeted drug therapies
coming on the market.
These won't necessarily cure cancer, Rella said. But they'll let
patients live longer and with far fewer side effects than the old
forms of chemotherapy.
Levine, of the UConn Medical Center, said genetic testing may let
doctors better match the drugs available to specific cancers and
specific patients, rather than using a one-size-fits-all approach.
And as new screening tests become available -- even for
hard-to-diagnose cancers like ovarian cancer and lung cancer --
there will be new rounds of talks and classes to teach people about
them. Howard said the recent declines in cancer mortality prove this
can be done.
"Either we're doing a better job at educating the public than I
thought, or people are reading about these screening tests, coming
to our offices and demanding them,'' he said. |
